Here we can give any valid Pokemon name and we will get our desired result.Īn important point to remember in GraphQL API testing is that whether the execution is successful or not it will always give a Status code as “200”. One important point to note here is that to test a GraphQL API you must have some basic understanding of its schema like what data type is used for which variable field. It will fetch all the details related to this Pokemon.

I have created a variable as “$Name” which is of string type as per the internal implementation of API and in the variable section provided its value as “Pikachu”. For demo purposes, I am using open-source Pokemon API.Ĭonsider the case where we want to fetch complete information about a Pokemon based on the name provided. Now Suppose you want to test a query with different variable values like data-driven API testing, How would you do that? Postman provides GraphQL variable section where you can either directly put the values or can drive data from global variables. I am using the below Open source GraphQL API for demo purposes: query field in your query and you will get your required information, so you observe that no over-fetching of data, no multiple end-points, Hence execution time is less. In simple words Query in GraphQL is used to fetch data while Mutation is used to perform insert/Update/Delete Operations. However, two important terms to note for GraphQL are Query and Mutation. We Can use postman to test GraphQL in the same way as we test Rest Services. Several big companies like Facebook, GitHub, Airbnb, Atlassian, Paypal, and Plural sight are listed as GraphQL customers on their Site. GraphQL is quickly making its place in the industry. Why it is important for a QA to know about GraphQL?Īs a QA we should be aware of new tools and technologies which are in high demand. This can be done by masking your REST endpoint into a GraphQL endpoint using Root resolvers. GraphQL and REST can co-exist in the same stack. However, it is important to note that GraphQL is not the definitive replacement for the rest API.

It allows developers to add new fields and types without impacting existing queries.

REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request.

Apps using graphQL are fast and stable because GraphQL queries return exactly what you need, Not More Not Less.

It is becoming a preferred alternative to Rest Services as it gives the ability to front-end developers to query only the required information through a single end-point. I'll further explain this using an example.Ī front end developer wants to fetch just the userName of a user in the database.GraphQL is an open-source data query and manipulation language for API. There is the problem of overloading information (mentioned earlier). In a typical REST API-based application, data is fetched from the back end and displayed on the front end.

Obtaining a JSON web tokens (JWT) for users in case of authenticated requests.

Making CRUD requests using both the Strapi GraphQL playground and Apollo GraphQL in a Vue.js app.

How to use of Apollo in Vue.js applications to make GraphQL queries to a Strap backend server.How GraphQL helps solve this problem and how implementing GraphQL in Strapi is even easier than we think.When fetching data from an extensive REST application with many database relationships, there is can be an information overload problem. REST API design pattern is one of the best practices when building API’s for the back end of any application.
